Title: Improvements in two-stroke cycle internal combustion engines
IPC: F02B25/00
Filed: 1920-09-03
Abstract: 151,009. Spuhler, V. Sept. 3, 1919, [Convention date]. Addition to 102,956. Two-stroke-cycle engines.-The engine described in the parent Specification is modified by utilizing the interior of the piston as a pump space, crankcase compression being dispensed with. A piston 2, Fig. 1, slides over a fixed head 34 having passages 10, 8' which communicate through ports in the walls of the piston and cylinder with supply chambers 29, 28 for air and combustible mixture respectively. The charges enter the combustion space, the air in advance of the combustible mixture, through passages 8<1>, 9 and a port 25 which registers with a piston passage 6 opening into the cylinder through a central orifice 8. The Specification as open to inspection under Sect. 91 (3) (a) describes the engine shown in Fig. 1 (Cancelled). It comprises a piston reciprocating over a fixed head 24 having passages 25, 26 communicating with passages 8, 13 for air and combustible mixture respectively. The air charge enters the pump space 29 through a port 7 in the piston, passages 6, 5 and 9 in the cylinder wall, the chamber 27 and the passage 25. Combustible mixture enters through the port 12a in the piston, a passage 11 in the cylinder wall, the chamber 28 and the passage 26, the admission of the mixture being delayed so that it remains in the passages only, none of the mixture entering the pump space. Charges enter the combustion space when the air passages 4, 6 communicate with one another through a port 20 in the piston, and when the combustible mixture transfer, passages 11, 15 register with a piston port 12. Scavenging air enters the combustion space in advance of the combustible mixture. This subject-matter does not appear in the Specification as accepted.

Title: Terminal air outlet device of an air distribution system
IPC: F24F11/76
Filed: 1974-06-10
Abstract: 1478343 Air outlet devices from air distribution systems CAPE AIR CONDITIONING (PTY) Ltd 10 June 1974 [11 July 1973] 25629/74 Heading F4V  A device in the top corner of a room can discharge air (i) downwardly along a wall and window and (ii) horizontally along the ceiling. As shown in Fig. 1, for heating a room, heated air is supplied through a pipe 18 to a housing 12 and discharged downwardly as indicated at 30 through an outlet 20. As shown in Fig. 2, for cooling the room an increased supply of air (which now is unheated or has been cooled) is supplied to the housing. This increased supply pivots a biased plate 26 to the position indicated in Fig. 2 and the air discharges both horizontally as indicated at 34 through an outlet 22 and also downwardly through outlet 20. Fig. 3 shows a different air discharge device. Air supplied through a pipe 62 to a housing 38 can be discharged downwardly through a first outlet 46 and diffuser 50 and can be discharged horizontally through a second outlet 48 and diffuser 52. Outlet 46 is controlled by a pivoted closure member 54 operated by a rod 56 and bellows 60. Outlet 48 is controlled by a closure member 68 which is gravity biased. The closure member 68 has a striker arm 72 which can be acted on by a plunger rod 74 of a thermostatically controlled actuator 76. When the room becomes too cold, the actuator 76 causes its rod to close the member 68 against the pressure of air issuing from the opening 48. The rod 74 carries an arm 78 which operates a microswitch 80 to switch on an electric heater 64 in the air intake pipe 62. The heated air flowing through the pipe causes the bellows. to expand and open the closure member 54. Fig. 7, (not shown) illustrates supply of air to devices (114) of the kind shown in Figs. 1 and 2. The devices are supplied from volume control units (112) each of which contains a temperature control means. Air supply to the units (112) is from high pressure shafts (108) via expander units (110). The shafts (108) are in a lift shaft (106). Fig. 8 (not shown) illustrates supply of air to devices (130) of the kind illustrated in Fig. 3. The supply is from a central main supply duct (120) via a volume regulator (124) controlled by a static pressure regulator (126) so as to maintain a constant pressure in the branch duct (122).
